Tankless heaters come in all different sizes. There are small water heater units, designed for point-of-use that only draw 110-120 volts.
The first step in determining which size water heater is right for you is to understand what you'll be requiring from the tankless. If you're looking for a larger unit, you should check out our tankless buyer's guide. But if a 110-120volt water heater meets your needs, then read on . . . this article was written for you.
110-120Volt Tankless Water Heater for Showers
Look, we're not going to lie, if you're not in the tropic and shopping for a 110-120volt tankless water heater for your home shower you'll most likely be disappointed with the results. 110-120volt's just isn't a lot of power to deliver a hot shower beside tropic area.
It can, however, get things going until your main water heater can take over, but most of the point-of-use heaters of this size are designed to be used for a single sink. In most situations, that means hand washing.
Although, there are exceptions. If you live in an area where the incoming water temperature is high, a 110-120V tankless such as JNOD XFJ135KH may be able to take a long shower. But if you live in Alaska, or most anywhere else, these units just won't be able to get the job done.
Best 110-120 Volt Tankless Electric Water Heater
The best 110 Volt tankless we've been able to find is the XFJ135KH by JNOD. Although the sales material lists this unit as a 120v tankless, JNOD has tested it to operate at 110v (more on this below).
The XFJ135KH is hydraulically controlled, making it incredibly quiet. It has a stainless-steel cup with copper heating element and with plenty of built-in safety features, and the superior design and workmanship means this unit is suitable for residential or commercial use.
Electric or gas? Which is better? In reality, there is no single answer to this question. The following factors all play a role in choosing what type of tankless water heater is best for your needs:
1.Efficiency / Operating Cost: While gas tankless water heaters are certainly more efficient than their tank cousins, their efficiency usually peaks at 80-85%. Conversely, most electric tankless water heaters are 98+% efficient. electricity costs are more stable and projected to rise much slower than gas rates in future.
2.Installation: Gas tankless water heaters have complex venting and combustion air supply requirements, especially when installed in a confined space, is that these requirements can make installation very expensive. Electric tankless water heaters are very small, and they can be installed in a closet, under a sink, in a crawl space, or a wide range of other areas where a traditional tank or gas tankless cannot. the installation of an electric tankless water heater is generally much cheaper than the installation of a gas tankless water heater.
3.Maintenance, Service Life and Warranty: Electric tankless water heaters require very little maintenance. In fact, other than cleaning the inlet screen filter occasionally. On the other hand, gas tankless heaters should be inspected annually by a trained technician to ensure safe fuel combustion and performance.
4.Environmental Impact: Electric water heater is no greenhouse gas emissions, small size reduces environmental footprint in manufacturing and ultimate disposal - future electricity generation to come from green sources such as solar, wind, and wave energy, gas water heater produces greenhouse gases and increases reliance on fossil fuels

Yes, but a tankless water heater does more than save you money.
Savings: Space
Since tankless water heaters do not have tanks, they take up less space. You don’t need to have a utility room or area in the garage for your water heater. Your tankless water heater can be stored in a closet or under the sink. Extra space is valuable these days, especially if you’re living in a smaller home or condo.
Savings: Energy
Traditional water heaters hold around 30-50 gallons of water and keep it heated until you’re ready to use it. Depending on the size of your family and the amount of water your family uses, this could be costly. (Did you know that water heater energy usage is the second-highest source of energy use in the average home?) Tankless water heaters don’t hold water, so they heat the water as it comes in—no constant energy to keep 15 milk jugs’ worth of water hot.
Savings: Time
Tankless water heaters save you time in the morning because the water is heated as it comes through until you are finished. While a traditional tank does have hot water on demand, that’s only until the tank runs out. Then you have to wait for the tank to refill and warm up the water. Tankless heaters don’t have that lag time because there’s unending water flow from the tank to the tap.
Savings: Money
Most new homes have a traditional water heater already installed when you move in. If you’re looking to replace the traditional tank, however, there is some work required. While installing a tankless heater might present a higher price tag than expected, the overall financial gains will overcome that deficit. It will raise the initial investment, but it’s an investment worth looking into for your home and your family. When comparing the overall savings of space, energy, time, and money – the savings really can add up.

The operation of an electric water heater is essentially the similar as that of a gas heater. It heats the cold water inside the pipe using the electric heating elements after bringing it in through the dip tube. Through the heat-out pipe, hot water rises in the tank and is transported throughout the house or shower .
It with two pipes— one for cold water inlet and the other for hot water outlet— makes up the geyser. It is equipped with thermostat-controlled heating components. Water is not heated above a predetermined temperature value by the thermostats. Typically, a metal casing is used to enclose the tank, which is then covered with an insulating material.
Jnod electric geyser is the tankless ,which is no need to pre-heat the water. The hot water can be come out instantly. It has temperature constant function,the temperature difference is only ±1 degree Celsius. Very comfortable and convenient .
When it comes to instant electric water heater, one of our biggest concerns is the service life of the product, HOW LONG SHOULD YOUR TANKLESS WATER HEATER LAST FOR? Generally speaking, if water quality is good, our heating element can use 8-10 years is no problem. So how do we ensure our product service life?
Firstly, JNOD with special and unique technology in patent heating element, the first cast aluminum heating element technology applied the patent in China. Our patent heating technology--cast aluminum with long lifespan,anti- limescale and high efficiency . We use the patent to make customers to enjoy the best hot water supply.
Second, we have very strict quality control process. We do 100% test for main parts(PCB aging test lasting for 8 hours), we do 100% test for finished product on assembly line and Comprehensive test bench automatic record the testing data.
Third, unlike conventional water heaters, high efficiency models have lower maintenance needs. Advanced technology is used to produce these heaters. Manufacturers adhere to high standards that guarantees efficiency in hot water supply. It also lowers the need for frequent maintenance.
We always put safety and quality at the first position.
Quality is our life.
Tankless Water Heaters, are appliances that produce hot water only when called for. Unlike conventional units that keep heated water in a tank that typically holds 40 to 80 gallons, a tankless unit heats water quickly on demand. And consumes less energy because you pay to heat only what you use. Reduced energy consumption means lower utility bills. In addition, a well maintained tankless system can have a life span that’s twice as long as a conventional storage water heater.
Basically, there are two types of tankless units:
Point-of-use water heaters are small enough to fit in tight spaces, typically under the kitchen sink or other areas in the home where hot water is needed. Incorporating several point-of-use units can reduce water heating costs significantly.
Whole house units are capable of simultaneously meeting hot water requirements at several locations, such as your dishwasher and shower.
Sizing is based on the flow rate that’s required and the temperature rise that’s needed. The flow rate is the amount of water that’s needed at any one time, and the temperature rise is the difference between the temperature of the water coming into the home and the temperature of the water flowing from the faucet. If the temperature of water coming into your home is 20 degrees, and you want water that’s 60 degrees at the faucet, the rise would be 40 degrees.
Are you considering a tankless water heaters? We can recommend a tankless system that meets the specific requirements of your home. Please contact us to get the details.
When buying a tankless water heater, most people don’t know what size tankless water heater they need.
If you are looking to install tankless electric water heater and you’re unsure of which size you should buy, here are some factors you should take into account:
- The size of your house
- Flow Rate (GPM): How much hot water you will need at any given time
- Temperature Rise (ΔT): The difference between the incoming cold water temperature and the desired temperature
Your Household Size
If water heater is too small, it will result in it not being able to produce enough hot water for your household demand. For example, you might not be able to run more than one shower at a time, especially in the freezing winter.
On the other hand, water heater is too large, it will end up being more costly than necessary, since you will be paying more upfront for the larger size (although it could be useful if you plan to upsize your home later).
Hence, to work properly, a tankless water heater needs to be just the right size to meet your home's hot water demand.
Rate of Water Flow
Tankless water heaters are often referred to as demand water heaters. On-demand refers to having continuous hot water output for as long as the hot water tap is open. However, having multiple hot water taps open together will reduce the hot water output. Having too many hot water taps open at once will produce lukewarm water if the tankless water heater’s output capacity is exceeded.
To help you estimate the flow rates of most of your faucets, we shared some typical flow rates below. The actual flow rates may be different for your house and different appliances.
Temperature Rise
After you have calculated the flow rate of every faucet in your house, you must now determine how much heat your heater needs to generate to give you the required heat in your water outlets. We’ll take into consideration the temperature of the water that flows into your home and the temperature of the water that you want to flow out of your tap to determine the required temperature rise.
